a wider use.

In the following detailed description reference 1s made to theaccompanying drawings,

in which:

Figure l is a plan; Fig. 2 is a front sectional elevation on the lineIIII of Fig. 1; Fig. 3 is a right end elevation withsome of the partsbroken away; Figs. 4 and 5 are details in section ahd elevationrespectively of one of the supporting sockets of the cathode-carryingframe; Fig. 6 is a small portion of a front elevation; Fig. 7 isa detailshowing a partial end elevation of one of.

the cathode-carrying wheels; Fig. 8 is a sectional view on line VIHVIIIof Fig. 7, showing the springs fixed; Figs. 9 and 10 are similar viewsshowing the springs movable and Figs 11 and 12 are similar views showingan alternative construction of the same parts.

The tank 1 has secured to inner opposite ends a pair of socket pieces 2,each of which removably holds a bearing block 3 for the journal 4 of thecathode-carrying frame or rack which is composed of the shaft 4 and apair of end wheels 5 which are exactly alike and which are rovided withnotches 6. There is a spring E for each notch which tends to presstoward one side of the notch so as to clamp the bars or rods 8 which arebeing plated, as shown clearly in Fig. 7.

The shaft 4., exceptin its bearings, and the end wheels are covered withan insulating material 9. This may be effected by a coating of liquidcelluloid, leaving only the springs 7 exposed to the depositing actionof the current in the plating solution and when they become too badlyincrusted they are easily replaced.

When rods of a larger or smaller diameter are to be plated the springs'3 may be attached toa ring 10 as shown in Figs. 9

and 10. This'ring is provided with slots 11 and it is held by screws12the construc-- tion permitting the springs to be bodily adjustedto andfrom the sides of the notches against which the rods are clamped. Forconvenience in counting an extra wide space 6 may be left between everyten notches of the frame.

The cathode-carrying rack or frame has at one end a pingear composed ofa rim 13 and pins 14, the rim being secured by studs 15 to one of thewheels 5. A horizontal shaft 16 having a drive pulley 17 on its outerend and a spur gear 18 on its inner end is carried in a bearingblock 19which is mounted on the tank. The shaft is slidable lengthwise in itsbearings so as to permit the two gears to be thrown into and out of meshwith each other-one of a pair. of pins 20 in the bear ing blockcooperating with one of a pair of annular grooves 21 in the shaft lockedin either of these positions.

The anode rods 22 and anodes 23 are the usual construction. The heightof the solushaft to hold the Specification of Letters Patent.Pattentedsept. 28, 1915.

tion is indicated by the line S-S. The

bearing blocks 3 have retaining screws 24;

which enter grooves 25 near the ends of the.

journal 4. and they are also provided with contact rods 26, the upperends of which fit sockets 27, of the return leads 28. By thisconstruction the entire cathode-carrying rack or frame is insulated,except the small retaining contact springs 7, as already pointed out. Bydisconnecting'the leads 28 the oathodecarrying frame with its bearingblocks and connecting rods carfbe readily lifted from the tank forrepairs or to permit the tankto be used in the ordinary Way. An

alternative construction is shown in Fig. 11 in which springs 7 are usedto clamp one side of the rods that are being plated instead of clampingthem iirthe notches 6.

Sutlicient current can be carried to the rods to plate them in onerevolution of the.cylinder, making the action of theapparatuscontinuousthe attendant removing the plated rods from thatportion of the rack which is above or out of the solution and putting innew rods in their place. A. guard strip 29 secured to the tank as shownin Figs. 1

and 6 is provided to keep the rods out of the gears. j ,What Iclaim is:

1. In an electro-plating device, a revoluble cathode-carrying frame orrack comprising a shaft; a pair of wheels secured to said shaft-the rimsof said Wheels being provided with a plurality of recesses or notches; acorresponding plurality. of springs secured to said rims and adapted topress toward one side of said notches, whereby a plurality of rods orbars may be held in longitudinal arrangement with relation to saidshaft.

2. In an electric-plating device, a revoluble cathode-carrying frame orrack comprising a shaft; a pair of Wheels secured to said shatt-the rimsof said Wheels being provided With a plurality of recesses or notches; as irings secured to said rims and adapted to press toward one side ofsaid notches and means for bodily adjusting said springs to and from thesides of said notches.

, 3. In an electro-plating device, a revoluble cathodecarrying frame orrack com prising a shaft; a pair of Wheels secured to shaft; a pluralityof springs secured the rims of said Wheels, all of said parts exceptsaid springs being covered with a coating 'of insu ting material-wherebya plurality of ro s or similar articles to be plated may be held intheplating solution and revolved with only the contact springs of theholding device subject to the action of the current.

4;. An electroplating device comprising a tank; pair of socket piecessecured to inner opposite sides of said. tank; a revolu bincathode-carrying rack or frame; bearing blocks "for the aXis of saidframe-said be ring blocks being removably held in and supported by saidsocket pieces; a gear rated on said frame concentric with its is; adrive shaft mounted on said tank can corresponding plurality of and agear on said shaft said driye shagft being shdable in its bearings tobring said gears into and out of mesh with each other.

(pin a plating device, the combir; vtion of the following elements: atank; a pair of socket pieces secured on inner opposite sides of saidtank; a revoluble cathode-carrying rack or frame supported by saidsocket pieces a gear mounted on said frame or rack by means of which itis turned; a shaft mounted on said tank and a gear on said shaft saidshaft being slidable endwise in its bearing to bring said gears into andout of mesh with each other and having an annular groove formed thereinand a locking pin adapted to enter said groove to lock said shaft in aposition with said gears in mesh.

6. In a plating device, a revoluble cathode-carrying frame or rackprovided with a plurality of pairs of gripping contact (30 springs, thesprings of each pair being secured to opposite ends of said frame.

7. In a plating device, a revoluble cathode-carrying rack or vframeprovided with a plurality of pairs of gripping contact at springs thesprings of each pair being secured to opposite ends of said. frame, in,combination with a gear on said frame ccncentric with the axis thereof;drive gear in mesh with said framegear and a guard interposed betweensaid springs and said gears.
